Woke up this morning (always a pleasant surprise ay this age) and had this thought.
First , some Background. I'm having trounle with Achilles Heel, and stretching and strengthing it. I use trainer slowly and one of those rubber ropes given to me from a PT session. (hook my toes around it, and flex my foot back forth). Worse, I'm an Engineer by trade and am going into work today so experiments are on my mind.
As trainer gets boring, and though its nice compared to Colorado, I still can't get out-doors all I want.
So..
If I attached one of 'those rubber ropes' used in PT - to my waist and then to something solid behind me acting as a spring - would that represent uphill or just wind?
If I remember correctly, we used something like this back in high school training for track.
HHmmmmmm.

thoughts?
Of course skeptics would just say I'd fall flat on my A**.
